CATALYST BASED ON FERRIERITE/IRON FOR CATALYTIC REDUCTION OF NITROUS OXIDE CONTENT IN GASES, METHOD FOR OBTAINING SAME AND APPLICATION
С катализатора се намалява съдържанието на двуазотен оксид в газове, обработвани при относително ниски температури, чиято активност е слабо чувствителна на наличието на водната пара, има висока устойчивост на хидротермално разрушаване и е получен отжелязо-обменен фериерит. Изобретението е приложимо...

| description | С катализатора се намалява съдържанието на двуазотен оксид в газове, обработвани при относително ниски температури, чиято активност е слабо чувствителна на наличието на водната пара, има висока устойчивост на хидротермално разрушаване и е получен отжелязо-обменен фериерит. Изобретението е приложимо за обработване на газове, съдържащи N2O, като газове от производства за получаване на азотна киселина, както и газове с високо съдържание на N2O, отделяни при окисляването на органични съединения с азотна киселина.
The catalyst reducing nitrous oxide content in gases operating at relatively low temperatures, whereof the activity is hardly sensitive to the presence of water vapour and highly resistant to hydrothermal degradation and is prepared from iron-exchanged ferrierite. The invention can be applied for treating gases with low N2O content, such as gases coming from the workshops making nitric acid as well as gases with high N2O content emitted during oxidation of organic compounds by nitric acid. |
